3-dimensional molecular level ordering of polymers is challenging objective to maximize their performance and efficiency in current research of polymer science. However, the precise arrangement of polymers at molecular-scale is most demanding due to the entropically favorable chain entanglement. Furthermore, especially for the polymeric materials, the industry requires the design and fabrication of crystalline polymers with molecular-level precision at a reasonable cost. To meet these challenges, we have generated 3-dimensional molecular level ordered polymers using a cost effective and simple chemical crosslinking. The controlled crosslinking reaction at molecular-scale effect on the crystallinity of polymers, leading to the sub-nanometer level ordered structures. This simultaneous arrangement resulted in 3-dimensional molecular crystal structures in polymers with a primary metallic crystalline structure such as hexagonal close-packed and face-centered cubic structure. The morphologies were studied with a high voltage electron microscope, and coupled with X-ray diffraction. In addition, the optical analysis was performed by Raman, FT-IR and UV-Vis-NIR spectrophotometer. Moreover, the electrical conductivity of crystalline polymers were analyzed by optical reflectance and I-V characteristics.
